Want to wake up a CE device at a future time (even if it is suspend), then use the CeRunAppAtTime but instead of running an app use a named event, this allows an application to wake up the device at a set time and also trap the wake event without spawning another process:
SYSTEMTIME time;
CTime nextWakeUpTime;
// get local system time and convert time to CTime for now
GetLocalTime(&time);
CTime now(time);
// 30 minutes in the future
nextWakeUpTime=now;
nextWakeUpTime+=CTimeSpan(0,0,30,0);
// convert to systemtime
nextWakeUpTime.GetAsSystemTime(time);
// set for wake up !
CeRunAppAtTime(TEXT("\\\\.\\Notifications\\NamedEvents\\SCHEDULE_WAKEEVENT_EVENT"), &time);
HANDLE wakeEvent = CreateEvent(NULL, FALSE, FALSE, SCHEDULE_WAKEEVENT_EVENT);
// wait for wake up!
if (WaitForSingleObject(wakeEvent, FALSE, INFINITE) == WAIT_OBJECT_0)
{
// sheduled wake up
}
